Abstract
The invention discloses a mold applied to a production process of automotive interior parts. An exhaust hole is arranged on the mold, the exhaust hole is connected with an exhaust pipeline, and the pressure in the exhaust pipeline is smaller than the atmospheric pressure; and the exhaust pipeline is connected with a vacuum pump. The mold disclosed by the invention further has the characteristics of low manufacturing cost, obvious exhaust effect, long service life and the like. After the exhaust structure uses the vacuum pump to exhaust, the blockage phenomenon of an exhaust slot is further relieved, the injection molding pressure can be relatively smooth, an important role is played in stabilizing the quality of injection-molded products and reducing the scrappage of the products and the cost is further reduced.
Description
Technical field
The invention belongs to a kind of manufacturing equipment technical field that is applied in the automotive upholstery production technology, specifically, relate to the mould that is applied in the automotive upholstery production technology.
Background technology
At present, the manufacturing equipment technical field in being applied to the automotive upholstery production technology is especially to the production technology of automotive plastic parts; Mould is most important, and in the prior art, mould is made up of upper die and lower die etc. mostly; In process of production, through operation auxiliary machinery equipment, according to the shape of mould; Raw material or woolen cloth are arranged between the fixed half and moving half, handle lifting or patrix and counterdie then and carry out joint movement, accomplish the manufacture process of workpiece.But in the prior art, existing mold has following technological deficiency:
Adopt mould of the prior art, after the manufacture process of accomplishing workpiece, patrix is removed, and workpiece is taken off from counterdie; Usually find the surface of workpiece, promptly on the binding face of workpiece and patrix, air pocket, aperture or pit usually occur; Cause workpiece quality defective, need workpiece to do over again, when serious; To cause workpiece to be scrapped, and waste raw material greatly, improved the producer's manufacturing cost, have a strong impact on the production efficiency of automotive upholstery.
Summary of the invention
Technical problem to be solved by this invention is, adopts mould of the prior art, makes on the binding face of workpiece and patrix; Air pocket, aperture or pit usually occur, cause workpiece quality defective, need workpiece to do over again; When serious, will cause workpiece to be scrapped, and waste raw material greatly, improved the producer's manufacturing cost; Have a strong impact on the technical problems such as production efficiency of automotive upholstery, and the mould that is applied in the automotive upholstery production technology is provided.
Technical conceive of the present invention is that the outer surface of automotive upholstery is the important component part that constitutes the automotive trim visual effect; If flaw with the quality that directly influences car load, directly influences the understanding of consumer to vehicle; Technical conceive of the present invention is, with offering pore on the mould, when occurring bubble or air pocket on the workpiece; Gas will be discharged through steam vent, discharge more smoothly in order to make gas, set up vacuum plant; With the automobile sucking-off, guaranteed that like this workpiece outer surface makes according to design effect.
Technical scheme provided by the present invention is, is applied to the mould in the automotive upholstery production technology, and said mould is provided with steam vent, and said steam vent connects gas exhaust piping, and the pressure in the said gas exhaust piping is less than atmospheric pressure.
Said gas exhaust piping connects vacuum pumping pump.
Said mould comprises upper die and lower die, and said upper die and lower die are installed relatively, and the side of said patrix is provided with steam vent.
The front of said counterdie is provided with air discharge duct, and the side is provided with steam vent.
Said steam vent and gas exhaust piping are tightly connected.
The said upper die and lower die back side connects exhaust main.
The steam vent of said upper die and lower die side connects exhaust main through gas exhaust piping.
The all corresponding seal groove that is shaped on of joint between the said upper die and lower die.
Adopt technical scheme provided by the present invention, can effectively solve and adopt mould of the prior art, make on the binding face of workpiece and patrix, air pocket, aperture or pit usually occur; Cause workpiece quality defective, need workpiece to do over again, when serious, will cause workpiece to be scrapped; Waste raw material greatly, improved the producer's manufacturing cost, have a strong impact on the technical problems such as production efficiency of automotive upholstery, eliminate the flaw that automotive upholstery shows appearance outward; Promote the quality of car load, promote the understanding of consumer, simultaneously vehicle; The present invention also has, and low cost of manufacture, exhaust effect are obvious, characteristics such as long service life.After this exhaust structure used the vacuum pumping pump exhaust, the choking phenomenon of air discharge duct was further alleviated, and injection pressure can be compared steadily, to stablize the injecting products quality, the minimizing product rejection rate plays an important role, and has further reduced cost.
Description of drawings
In conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is a structural representation of the present invention;
Wherein, 1 is patrix; 2 is counterdie; 3 is steam vent; 4 is vacuum pumping pump.
The specific embodiment
Manufacturing equipment technical field in being applied to the automotive upholstery production technology, especially to the production technology of automotive plastic parts, the existing mold design is unreasonable, no air discharge duct, getting product has the gas trace.The means that solve are, on mould, increase air discharge duct, have solved product gas trace problem.According to the mould product technological requirement, designing and arranging air drain track, measurement size; Mill out air discharge duct with equipment, leave the air discharge duct that meets the mould process requirement at last.
As shown in Figure 1, technical scheme provided by the present invention is, is applied to the mould in the automotive upholstery production technology, and said mould is provided with steam vent 3, and said steam vent 3 connects gas exhaust pipings, and the pressure in the said gas exhaust piping is less than atmospheric pressure.Said gas exhaust piping connects vacuum pumping pump 4.Said mould comprises patrix 1 and counterdie 2, and said patrix 1 is installed with counterdie 2 relatively, and the side of said patrix 1 is provided with steam vent 3.The front of said counterdie 2 is provided with air discharge duct, and the side is provided with steam vent 3.Said steam vent 3 is tightly connected with gas exhaust piping.Said patrix 1 is connected exhaust main with counterdie 2 back sides.The exhaust of said patrix 1 and counterdie 2 sides
